General Description

  • This endpoint filters a dataset and creates a snapshot of the filtered data in your account.
  • The job runs asynchronously and can take up to 5 minutes to complete. If it exceeds this time, it will be cancelled.
  • Charges apply based on the size of the snapshot and per-record pricing.
  • Filters can have up to 3 levels of nested filter groups.
  • You can upload CSV or JSON files for efficient filtering when handling large sets of values.

​
File Format Requirements

  • First line must be a header matching the field name in your filter.
  • Each following line contains a single value.
Example: industries.csv
industries:value
Accounting
Ad Network
Advertising

​
